Seedlings with submembr. ovate to lanceolate deeply toothed lvs, deeply lobed near base, passing rapidly into narrow-linear lvs. Unbranched juveniles with narrow-linear deflexed lvs up to 1 m. or more long, distantly sharply toothed, with stout midrib. At branching stage the lvs become shorter, c. 30-15 cm. long, and may be unifoliolate (var. unifoliolatum Kirk For. Fl. 1889, 61) or 3-5-foliolate (var. trifoliolatum Kirk loc. cit.) or mixed. Flowering is exceedingly rare in the unbranched, rare in the branched juvenile stage. Adult trees round-headed, with lvs c. 10-20 × 2-3 cm., narrow elliptic-cuneate to lanceolate or linear-obovate, acute or obtuse, entire to sinuate or coarsely serrate. Umbels terminal, irregularly compound; primary rays c. 5-10, c. 6 cm. long; umbellules sts racemosely arranged. Ovary 5-loculed, 5-ovuled, style-branches 5, connate, sts free at tips.
